Transthoracic echocardiography during prone position ventilation: Lessons from the COVID-19 pandemic.

Objective: The current coronavirus disease 2019 (COVID-19 outbreak) demands an increased need for hospitalizations in emergency departments (EDs) and critical care units. Owing to refractory hypoxemia, prone position ventilation has been used more frequently and patients will need repeated hemodynamic assessments. Our main objective was to show the feasibility of obtaining images to measure multiple parameters with transthoracic echocardiography during the prone position ventilation.
